2,603 PointsSQL Error: Unique Constraint Failed...but I haven't entered any values
I'm in the Creating and Modifying Database Tables course working on this challenge:
We're starting a rock collectors club! Can you create a 'members' table with the following columns: id, first_name, last_name, and favorite_rock. Also, make sure we only allow unique ids.
I'm entering:
CREATE TABLE MEMBERS (
ID SMALLINT primary key,
first_name VARCHAR(255),
last_name VARCHAR(255),
favorite_rock VARCHAR(255)
);
...and I get the error "SQL Error: UNIQUE constraint failed: MEMBERS.ID" A thread in StackOverflow is telling me that this is happening because I'm entering duplicate values in the primary key column, but I haven't entered any values. What's going on here?
